Introduction to the 17IPS72 Power Board , a Turkish electronics giant that produces TVs
An oscillator controller switches the primary side power MOSFET, passing pulsed DC through the high-frequency step-down transformer. On the isolated secondary side, heavy-duty Schottky diodes smooth the output into stable and 24V lines. Feedback loops utilizing an optocoupler track the 12V line to dynamically tweak the primary-side switching frequency, keeping the voltage rock-solid under load. 4. Integrated LED Backlight Driver
